Single-photon Avalanche Diode

Canon Spad Sensors.    View      

The SPAD sensor developed by Canon employs a proprietary pixel architecture that reflects photons inside the pixel in order to effectively detect photons across the entire region of effective pixels.

Under equivalent light conditions, the SPAD sensor can capture the same images as a conventional CMOS sensor while requiring only 1/10 of imaging area. This realizes an ultra-small design that can be installed even in small devices and can greatly increase sensitivity. Both static images and video images can be performed in low-light environments, including dark night conditions. By equipping cameras designed for low-light environments and other monitoring applications to this SPAD sensor, even video footage of low-light environments can be viewed as if it were recorded in bright areas, enabling identification of subject movement as though viewing with the naked eye in well-lit environments.
